Question

Find the perimeter of a triangle whose sides are $2 a + 3 b, b - a, 4 a - 2 b$ .

Open in App

Solution

As we know that the perimeter of a triangle is sum of length of all the sides. Hence,
Perimeter $= 2 a + 3 b + b - a + 4 a - 2 b$
$\Rightarrow 5 a + 2 b .$

Hence, this is the required answer.
